Trump speaks to Romney amid speculation on Utah Senate race

Mitt Romney, former governor of Massachusetts, addresses the Hinckley Institute of Politics regarding the state of the 2016 presidential race during a speech at the University of Utah in Salt Lake City on Thursday, March 3, 2016.

It was not clear if they discussed the Utah Senate race. Romney has been considering a 2018 run in Utah if Sen. Orrin Hatch retires. Trump has encouraged Hatch, 83, to seek another term.

Conway wouldn't say if Trump would support Romney in a potential Senate bid.

Romney fiercely criticized Trump during the presidential campaign.

Trump's former chief strategist Steve Bannon assailed Romney during a Tuesday rally for Alabama Senate candidate Roy Moore. Bannon attacked Romney as a "draft dodger." Romney received a draft deferment for his missionary work in France.
